Specification of Letters Patent.

Patented July 17, 1906.

Application filed September 27, 1905. Serial No. 280.343.

To all whom it may concern- Be it known that I, ARTHUR E. BENSON, a citizen of the United States, residing at Agricultural College, county of Oktibbeha and State of"'Mississippi, have invented an Imtween the shuttle and the edge of the cloth.

ing means such as herein If the filling is taut, the detecting action of the filling' fork is performed in a much better manner than if t e filling is slack, and slackness also permits the filling to twist or kink. When looms are provided with automatic filling-replenishing mechanism and with means to part the old filling end between the cloth and the shuttle, (upon filling replenishment,) it is of great importance to have the filling taut between the cloth and the boxed shuttlethat is, immediately after the shuttle is boxed for replenishment the filling is clamped first near the shuttle and thereafter it is parted between the clamp and the shuttle, and while still clamped the parted filling end is brought into the range of a temple thread cutter to be parted adjacent the edge of the cloth. Consequently if the filling is slack it may twist or kink out of reach of the clamping and parting devices, so that they cannot operate properly and filling end will break, the broken end often flying back to be woven into the cloth, making an imperfection therein. By my present invention the increase in the tension on the filling as the shuttle-boxes prevents such objectionable occurrences.

A loom provided with arting and clampefore referred to is shown in United States Patent to Draper, No. 683,423, dated September 24, 1901, to which reference may be had.

In accordance with my present invention the tension-controlling means is located on the shuttle and is automatically operated. as the shuttle is boxed.

The various novel features of my inven l tion will be fully described in thesubjoined specification and particularly pointed out in t e following claims. a

Figure 1 is a top plan view of the shuttlebox of a loom with a shuttle thereinembodying one form'of my invention, the shuttle and the front box-wall being partly broken out to show the operation. Fig. 2 is an enlarged top looin-shutt c with one form of my invention applied thereto; and Fig. 3 is a transverse section on the line 3 3, Fig. 2, looking toward the right. i

I have shown in Fi 1 a shuttle-box at the right-hand side of a loom, the box comprislan view of the deliveryend of a ing the fixed front wall 1 and cover or guardplate 2, mounted on the lay 3, the binder 4 and picker 5 being also shown, This construction is suitable for either a lain loom or one provided with automatic Hin -replenishing mechanism of the type s own 1nv United States Patent to Northrup, No.

529,940, and I have shown the shuttle 6 as of the automatically self-threading type, open at 7 to receive the filling-carrier 8 and having thread-delivering means, shown herein as a self-threading device 9 of any suitable construction. This device is adjacent one end of the opening 7 and in the opposite end of such 0 ening the shuttle is shown in Fi 1 as provided with holding-jaws 10 for 516 butt of the filling-carrier, all of substantially wellknown construction.

While I have shown a self-threading shuttle herein, my invention is not restricted to use therewith, as it can be used with facility in an ordinary loom-shuttle. The shuttle wood is cut away at 11 in front of the threaddelivering means 9, the filling 12 passing therethrough from the tip of the filling-carrier in usual manner to be delivered.

In accordance with my present invention I mount a spiral tension member 13 in the cut-away part 12 transverse to the path of the fillin and just belowit, so that the fillis delivered from the shuttle. One end of the spiral is attached to the shuttle-body, as at 14, Figs. 2 and 3, and its opposite end is secured to the inner end of the compressor 15, (shown as a short pin slidably mounted in a hole 16 .in the shuttle,) said hole being counterbored at its outer endto receive the head ing will raw between two adjacent coils as it,

safely be ell'ected.

17 of the compressor, the outer face of the head being rounded, Figs. 2 and 3. The expansibility ol the spiral normally maintains the coils thereol Far enough apart to let the filling draw through as freely as desired, and it also maintains the compressor in the position shown in Figs. 2 and with its ro'unded hrmd projecting slightly beyond the side of the shuttle. By )ressing the compressor inward the )iral 13 will be compressed and its coils thereby moved toward each other to increase the tension on the 'lilling and act as a drag thereon. This operation of the compressor is ell'ected herein by enga ement of the head 17 thereof with the inner iitce of the iixed wall ol" the shuttle-box. When the thread-delivering end of" the shuttle is ahead, as when entering the right-hand shuttle-box, the instant increase oi the tension as soon as the compressor-head engages the inner end of the box-wall l inlght tend to break thelilhng,

and 1 therefore make a longitudinal depression 18 in the wall from its inner end to the point at which the increase of tension may This, as shown in Fig. 1, is when the shuttle .is approaching the end of its llight, andas soon as the head of the compressor reaches the outer end of the de reS- sion 18 it rides up on the Face of thewal and is thereby forced inward, so that the member 13 increases the tension.

When the shuttle is boxed at the opposite side ol' the loom, the delivery end is nearthe .Jnouth of the box, and as the compressorhead will not engage the front wall ol the box until the end ol'- the shuttle llight approaches no (lo )ression or other change in such wall is usuall y necessary. For that reason I have not shown the opposite shuttle-box in the drawings with the filling taut, as at 1'2, Fig. l. The same is in the most ellicient condition for the cooperation of a thread clamping and 'As a. result, the; iilhng isdrawn properlyt'aut between the shuttle and the edge of the cloth, as i-n'Fig. 1. ing beyond the shuttle side,

parting device, such as previously referred to, ii the loom be so equipped or for engagement by the filling-fork in an ordinary loom.

llaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-, 1,

1. The combination, in an automatically scll threading loom-shuttle adapted to receive a supply oi" filling, of a tension device carried by the shuttle and inchuling a transversely-arranged spiral, the filling passing between adjacent coils thereof, and a compressor to move the coils toward each other and therebyincreasc the tension on theiilling.

2. The cmnbination, in an automatically self-threading loom-shuttle adapted to re ceive a supply of filling, of a spiral tension member arranged transversely to "the path of the filling, and a eonrressor connected with the said memher and laying a head. proj ecting beyond the side of the shuttle, inward pressure on the head acting to= c'mnprssthe spiral member and thereby increase the ten; sion on the filling.

3. The combination, in a loom-slmttlehaving guiding and. delivering means for the iilling, of atension spiral carried by the shuttle adjacent said means and adapted to receive the lilling between adjacent-coils, and a corn.

-pressorinovably mounted in the shuttle and connected at its inner end with the spiral, the outer'end of the eon'ipressor normally projectinward move mentof the com ressor pressing the coils ofthespiral toward each other, to increase the. tension on the lillingz.
